such as are used* inrailway cars, motor busses etcl,Y and has `for its' object,` a particularlytsimple `and eiiicient means for securinga detachable window stopto thefvvindow frame `or `post structure, and alsoa particularly simple and efficient means for holding the 'sashirom rattling and wathertight. A i i Theinvention consists in the novel features and in the combinations and constructions hereinafter set forth Vand claimed. i i In describing'this invention, reference is had to the accompanying drawings in lvvhichilike characters designate corresponding parts `in fall the views."\ 'Y Figure 1 is` afragmentarywelevation, partly 'broken away, of a Windovv` Structurehembodying my invention.

- Figure 2 is avertical sectional view taken substantially centrally of Figure l, looking `tothe right.

Figure 3V is Aan enlarged sectional vieu/taken on line-3 3; Figure 1. i? i i i i Figure 4 is a fragmentary Aedge view of thesash, the contiguous' parts of the Window frame being 1 Figure 5 is a fragmentary edgeview of one of kthe uprights fof theifvvindovv;"fraifneA or post structure.

The post structure is formed up of sheet metal v `and is here shown as rectangular in general form in cross section open at its outer side, and is set with its open outer side toward the Wall of the Window opening 5. It is securedin the window opening in any suitable manner as by screws passing through holes Ia therein intothe wall of the Window opening. The outer stop 2 consists of a iiange reversely folded from a flange 6 of the post structure I and extending beyond the inner Wall of the post I to lap the sash iV and form an outer stop therefor. This outer stop 2 is also i shaped to receive a holder 'I for a Weather strip 8 which engages flatwise against the outer `face of the stiles of the sash 4. This Weather strip may be of any suitable material, as felt or material Aformedjvvith anap orjbristles., I Y 1 i The inner-stop 3` is detachable and isiformed upfrom sheet `.metal-inthe general formo-fra .Uv shapedchannel. The Wall of the channeladf jacent thesash abuts edgewise againstr the post I and 4is provided at intervals with tongues 9 Iwhich enter slots I formed in the body I, the `tongues!) and slots,4 I9 serving. to locate the` stop`A 3. The outer side"of the detachable stop ,3 i s .provided with an extension 3,a which laps the upright en d Wallu of the .body I. The tongues are `L )rovideddon platesiia whicharesecured as by spot Welding` at 9b tothe detachablestop3. f

The detachable stop 3 is `secured to the t post structureby means which detachably interlock with the body I, and this means consists of oneor more plungers, as a plunger AII movable through openings in the bottom of the channel ofthe stop 3, theplungerhaving a buttonfor crossbar I2 at its innerendfand a head I3 at its outer end.` "Ihe ecros; barl moves through a slot I4 in the body'| upon "inwardl movement of the plunger',b and'into interlocking engagement-With the walls thereof -upon'a partial rotary movement, or quarterfturn of the plunger. This locking feature perse forms no parto-f this invention; but themounting of the "plungerl to" be presently described is one of the principal` features of this invention:

The plunger i's'mountedin a tubular guid'ei l5 surroundingithe plungerLand extending into'the channel of the detachable stop, the guide having anrinturned shoulder I 6 at its inner end through which the plunger slides, and having its outer end extending through an opening I'l in the bottom of the channel formation of the detachable stop, and secured to said bottom by an upsetting or riveting operation.

A compression spring I8,encircles the plunger andthrusts at its inner end against the shoulder I6, and at its outer end against the head I3. Obviously, inward movement of the plunger will plunger will interlock the cross head with the body I of the post structure, and the spring will f er cause the cross head I2 thereof to pass through i the slot I4, and a partial rotary movement of the hold the cross headA I2 snugly engaged with the l The sash is provided with a sash holder at each lower corner thereof. These sash holders may be of any suitable form, size and construction. They usually include a housing I9 mounted on the outer side of the bottom lower rail of the sash, a pinch handle or lever 20 pivoted to the housing, and operating motion transmitting means in the housing, or in the bottom rail of the sash to transfer the movement of the lever to a locking bolt 2|, this locking bolt being preferably located within the sash and movable through the edge thereof.

In the illustrated embodiment of our invention, the locking bolt 2| eXtendsthrough openings 22 in the wall of the post structure, that is, the wall opposed to the edge of the sash, and means is provided within the post structure for coacting with the bolt to press the bolt and hence, the sash outwardly against the outer stop to hold it from rattling, and also to hold ittightly closed so that it is weather tight when the sash is closed.

As here illustrated, the bolt 2| is provided with a beveled edge 2|a which coacts with means as blocks 2,3 located within the hollow post structure I* and secured thereto as by fastening members 24, these blocks having beveled faces 25 arranged to coact with the beveled faces Zia of the bolt 2|'.

As the sash holders are located at the extreme lower edge of the sash, means is also vprovided for pressing the upper portion of the sash against rthe outer sto-p when the sash is entirely closed, this means being carried by the detachable inner stop 3. 'Ihis means as here shown comprises compression devices as spring pressed shoes 26 located in each detachablev stop 3 and movable through slots 21 therein into engagement with the Stiles of the sash. These spring pressed shoes 26 are here shown as elongated and provided with eyes 28 at their upper and lower ends through which extend guide rods 29 extending forwardly and rearwardly between the front and rear walls of the channel of the outer stop, and springs encircling said rods and thrusting against the ends of the shoe 26.Y p

In the window here illustrated, there is a stationary upper sash 30, the bottom rail of which coacts with or laps the top railr3| of the sash yli, and these rails are provided with coacting weather tight or weather strip means 32 on their abutting faces. This weather strip means may be of any suitable form, size and construction.

The upper rail 33 of the stationary sash 30 is formed up of sheet metal and comprises a ange 34 for lapping the inner face of the top wall of the window opening, this flange 34 being secured to the wall of the window opening, as by screws 35. The top rail 33 is shown as formed up of two sheet metal parts to provide a hollow body having a reentrant glass receiving groove 36, these two parts having lapping iianges, or iianges lying one on the other which form the ange 34 of the top rail. The iiange 34 extends laterally or tangentially from the hollow body of the rail When the sash is closed, the sash holders owing to the wedging action of the bolts and the action of the compression devices 26 press the sash against the outer stop holding it weather tight,

and also against rattling. The compression device 26 also presses the top rail of the movable sash against the lower rail of the stationary sash 3U rendering the joint between the same weather tight when the sash is closed.

Owing to the particular means for holding the stop in position, the stop is iirmly and rigidly secured against reaction of the'sash due to the weclging action of the sash holders and of the compression devices-26 and at the same time, is readily detachable and replaced when desired.

What we claim is:

The combination of a window frame including a demountable window stop, inthe form of a channel and arranged with its open side toward the adjacent frame member, means within the channel of the stop and carried thereby for securing the stop in position, comprising a tubular guide fixed to the bottom of the channel of the stop and projecting toward the open side of the stop, a holding member slidable axially of the guide and operable to interlock with the frame through a slot therein upon successive axial and partial turning movements, the holding member having a head for fitting in the outer end of the tubular guide and exposed on the outer side of the bottom of the channel and a spring interposed between the head and the inner end of the tubular guide and acting to thrust the holding member outward.
